MARTIN S. SNYDER, OF CALGARY, ALBERTA, CANADA.

TIP.

To all whom it may concern:

Be it known that I, MARTIN S. SNYDER, a citizen of the United States, residing at Calgary, in the Province of Alberta and Dominion of Canada, have invented certain new and useful Improvements in Tips, of which the following is a specification, reference being had to the accompanying drawmgs.

This invention relates to certain improvements in tips, and has relation more particularly to a device of this general character especially designed and adapted for use in connection with crutches, and it is an object of the invention to provide a device of this general character having novel and improved means whereby the same, when in applied position, serves effectually to prevent slipping of the crutch when in use.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved tip whereby certain important ad vantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel featurese of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view partly in sectlon of a tip constructed in accordance with an embodiment of my invention and in applied position, the coacting crutch being shown in fragment; and

Fig. 2 is a view in bottom plan of my improved tip as herein set forth.

As disclosed in the accompanying drawings, B denotes a body or member formed of rubber or kindred material. The bottom or outer face 1 of the body or member. B is concave to assure suction action when the deviceis in use, and whereby means is pro- .vided to prevent slipping.

The upper opposite end portion of the body or member B is provided with a. longltudinally disposed socket 2 to receive the foot portion of the leg L of a crutch and the bottom or lower end portion of the body or member B is provided with a recess 3 in which is snugly fitted a plug 4 preferably formed of canvas or similar textile material.- The plug 4 extends slightly beyond the open Specification of Letters Patent.

face of the recess 3 so that requisite contact thereof may be had with the ground or other surface to further prevent slipping of the crutch to which the body or member B is applied.

5 denotes an opening connecting the inne ends of the socket 2 and the recess- 3 an arranged preferably, at the axial center thereof. The plug 4 is also provided with an opemng 6 in register or alinement with the opening 5 and disposed through said openings 5 and 6 is a metallic shank 7 having its outer end terminating substantially flush with the outer face of the plug 4. The shank 7 serves as a further preventative of slipping.

The inner end portion of the shank 7 is provided with a flat head 8 which snugly fits Within the socket 2 and contacts with the base of said socket when the shank 7 is applied. The end of the foot or leg L contacts directly upon the head 8 and protects the inner end of the socket 2 against wear or other injury by the leg or foot L.

The shank 7 may be readily removed by forcing the same inwardly so that a worm shank may be readily replaced in accordance with the requirements of practice.

as concentric to the recess 3 and which afford means to further facilitate the requisite gripping of the tip upon the surface with which the same is brought into contact.

From the foregoing description, it is thought to be obvious that a tip constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification Without departing from the principles and spirit thereof, and for' this reason I do not wish to be understood as limiting myself to' the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as here inafter claimed.

What is claimed is:

1. A tip of the class described comprising a body provided with a socket in one said body textile plug fitted within the recess, and a metallic shank disposed through the open- .ing of the body and through the plu the ing between the opposed ends of the socket and recess, a plug fitting within the recess, and a metallic shank disposed through the opening ofthe body and through the plug, the inner end of the shank being provided v ith a head overlying the inner end of the socket. I

3. A tip' of the class described comprising a. body having one end concave, said end being fprovided with a recess, the opposite end 0 the bod being provided wlth a socket, said b y having an opening communicatin between the opposed ends of the inner end of the socket, the. concave end of t I the bod being provided with a groove sub? stantial y concentric to the. recess.

In testimon whereof I hereunto aflix my signature in t e presence of two witnesses.
